| Hazama was a school active in the mid-Edo period that produced distinctive tsuba using sahari inlay. Sahari is an alloy of copper, tin, and zinc. They devised sahari inlay for tsuba inspired by the nunome-zōgan technique used on matchlock gun barrels. Their ancestors are said to have been gunsmiths from Kunitomo Village in Ōmi Province. Around the Genroku–Kyōhō era, Kunitomo Teiei entered the service of the Matsudaira family in Kameyama, Ise Province, and moved there from Kunitomo.This work is a large iron wari-kōgai with a polished surface, decorated with cloud motifs in sahari inlay. Sword fittings other than tsuba employing sahari inlay are rare. In 2004, it was attributed to the Hazama school and passed the Hozon Tōsōgu shinsa. |
